It's crazy that a 60 ton metal airplane can just fly

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics
- 3.1) NEW RULE as of 5 Nov 2024, trying it out
- 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct

Airplane engines have deceptively high thrust, imagine each one as a rocket and it'll start to make sense. The a380 (the big double decker) each engine produces around 350KN. When that thrust is applied to an 80kg human they'll experience almost 450Gs of force
In an extreme sense, imagine putting a little rocket engine on a paper airplane which will represent a high thrust to weight ratio
Your last description is essentially the idea behind the F-117a. That thing ~~isn't~~ wasn't flying, ~~it's~~ it was achieving escape velocity.
